; Test: ExternalConstant
|
|
;
|
|
; Description:
|
|
; This regression test helps check whether the instruction combining
|
|
; optimization pass correctly handles global variables which are marked
|
|
; as external and constant.
|
|
;
|
|
; If a problem occurs, we should die on an assert(). Otherwise, we
|
|
; should pass through the optimizer without failure.
|
|
;
|
|
; Extra code:
|
|
; RUN: llvm-upgrade < %s | llvm-as | opt -instcombine
|
|
; END.
